To my knowledge, no. I was searching for GTA 1 and 2 as well and could not find a legal way to purchase them for PC. Maybe someone has the games as a gift, so would probably sell this way. Or old still active keys sold in certain shops. But those are grey areas. There was also a period of time when Rockstar gave those games away I believe.
Whatever you do, I would be very careful not to fall in a scam trap. Also lot of free .exe downloads are probably infested with malware. The only way to play those games for me is, to emulate them.
I know it’s not what you asked for, but I remember a couple of years ago someone making a game heavily inspired by GTA 2. Never got around to playing it myself, but it looked good.
Can’t find it right now though. Googling gave me Glitchpunk, which looks similar, though not as I remember it. And apparently it’s stuck as early access and might be dead. Maybe someone else will remember that other game I remember.
